John, good news — I already have the 2Meg Agnus! (gotta 3000, remember) One thing I've always wondered about is filling Chip RAM with the beginning of my animation and Fast RAM with the next frames, then starting the animation. As Chip RAM frames are displayed, I can copy over them as soon as the screen address has moved on; when all Chip RAM has been shown, I already have some new frames in Chip RAM waiting to be displayed. Since the processor (we all assume by now) is slower at moving memory than we want, the screen pointer will eventually catch up with it, but by re-using "already displayed" frames we can certainly buy time and show sequences longer than would fit into 2 megs. (By the way — are you using an accelerated machine or a stock 2000? My 3000 would give much better performance) Again, I'm surprised though — am I really the first Amiga user with that much ambition? Hasn't anyone else wanted to get MUCH closer to real-time animation like we see on TV all the time? I'll give the Right Answers Group a call this week and see if I can talk with a techy person.
